Conclusions 1. The selection of the optimum parameters of local heating with gas torches makes it possible to induce compressive residual stresses of ≈0.5σT in the plates. To obtain the maximum possible magnitude of the compressive residual stresses, it is sufficient to heat the regions to comparatively low temperatures (400–500°C). 2. The maximum possible magnitude of the compressive residual stresses in axisymmetric heating of infinite plate does not exceed 0.6 of the yield stress of the given material. 3. The effect of external loading changes the fields of the residual stresses induced by local heating. In the range of external loads typical of fatigue of welded joints, the reduction of the maximum compressive residual stresses does not exceed 30% of their initial value.
